The 28-year-old actress - who is engaged to the heartthrob movie star - has revealed her closest pals often alert her paramours about her fiery side, claiming she can become extremely rowdy when angered.

'Pirates of the Caribbean' star Johnny, 50, is thought to have popped the question to Amber over Christmas last year and confirmed their engagement in April, but the blonde beauty admits her newfound celebrity hasn't had much effect on her standing in Hollywood.

Speaking in the new issue of W magazine, she said: "I haven't noticed any change in my career. And, for better or worse, I've always had a love life that seemed particularly salacious to some people. Before it was also seen as unconventional."

Meanwhile, the openly bisexual 'Paranoia' actress has defended her past romance with photographer Tasya van Ree, insisting she is not "ashamed" of their four-year relationship.

Amber explained: "I didn't want to look like I was hiding anything. I'm not, and wasn't ever, ashamed. I don't imagine myself, my work, or my life, fitting into any kind of standardized path. In fact, the idea of there even being a standard freaks me out a lot."
